Marcellus Compression Station

Orbital provided the civil, structural, piping, electrical and instrumentation design for a new Marcellus Compression Station. Orbital Engineering developed P&IDs and 3D modeling/equipment arrangements for the new facility, as well as, detailed design for the civil, structural, piping, electrical, and instrumentation for an accompanying project involving the installation of five gas compressors, gas pig receiver/launcher, suction/discharge scrubbers/filter coalescers, vapor recovery unit, three tank system, flare, flare knock out vessel, plus various ESD (Emergency Shutdown) valves, control valves and flow meters. Later in the design Orbital added glycol dehydration absorbers and reboilers.

Part of the design consisted of a substation that takes 138KV from the utility and supplies 4.16KV and 480 V to the plant. The design of the substation from the utility to the 480-volt was performed by Webnic. This includes the substation structures, breakers, transformers, 480-volt disconnect structure, grounding, lighting, static protection, and cable trench design.

Orbital Engineering’s mechanical department also provided a unique deliverable package for another plant expansion that included developing a Plant 3D catalog (spec) which contains all the necessary components to create an accurate, full scale Plant 3D model of the piping and supports (including future tie-ins) at each segment of each pipeline. The pipeline was segmented into four separate sites along the pipeline. Also inclusive to the package was: all BOMs, 2D piping plans and sections, piping isometrics, and support details (including foundations).

For each pig launcher/receiver (one 16”x20”, one 20”x24”), Orbital Engineering mechanical department provided a unique deliverable package that included: developing a Plant 3D catalog (spec) which contains all the necessary components to create an accurate, full scale Plant 3D model of the piping and supports. Also inclusive to the package was: all BOMs, 2D piping plans and sections, piping isometrics, and support details. Additionally, for each size of pig launcher/receiver, the Orbital Engineering civil department revised and optimized the skid steel, relocated the lifting lugs (per the center of gravity), and analyzed and revised the concrete foundation designs, ultimately reducing the size requirements which in turn provided a considerable cost savings to the client.
